Terra Firma recently did a crawl space drainage system for my home. Gage and his crew showed up right on time, did the job quickly, and cleaned up afterwords. Gage explained how everything works and answered all my questions to my satisfaction. I will definitely recommend Terra Firma.

You have an ace in Ryan Lahley. He is an outstanding young man. Treat him well! From the minute I contacted your company to the signing of the contract I was treated very well. I feel totally comfortable having TerraFirma take on my project. I like having the materials sent our ahead of time. The extra information was very helpful.

Chad and the entire crew at the site were very professional and knew what they were doing. They seemed to be very competent and worked together really well.

I was a little bit disappointed that I had to call back your crew to finish up the job. I don't blame the crew, but rather the management that tried to schedule what was supposed to be three days worth of work into two days. It sort of reeks of business "efficiency" without regard to the employee. I also would have appreciated having better oversight of the project, perhaps keep the sales person checking in. I don't particularly like these surveys. They seem to be a template device tailored for marketing. You'd be better off putting the human touch back into your business.

There were two parts: the basement waterproofing and the porch lifting. A young, minimally experienced crew was sent for the waterproofing. The Waterguard system we were expecting couldn't be installed and a surface-mount DryTrak was substituted. The sump pump basket wouldn't fit and had to be cut down by hand. Despite good intentions a water pipe was broken and the basement was flooded. There had been no preparation for cleanup of such a complication - no towels, no mop. For the porch lifting a single young man was sent and appeared adequately experienced. That process was performed flawlessly and without a hitch.

I cannot think of a more disgusting home repair than having to address a wet, smelly, nasty crawlspace. A place I never gave any thought to whatsoever. While all of our friends are traveling all over Europe this summer my husband and I have had an absolute ball watching the remake of our crawlspace. It has been extremely educational and fascinating to learn about the new technology. It motivated us to take care of all of the nagging little things we always put off like cleaning the vents, changing filters, getting carpets cleaned etc. It is so refreshing to have a spotlessly clean brilliant white, dry crawlspace. My entire house smells so fresh and clean. The energy is amazing. My favorite story was the day after TerraFirma completed the job we had an electrician come to install plugs in the crawlspace. He jumped out of the crawlspace and said "I love your crawlspace, I could hang out down there in my shorts". We love it. A million thanks. So much better than a fancy trip. Thank you to everyone at TerraFirm and most particularly to Bryan Cantrell and Chad LNU, foreman and crew that did the job. We commend all of you on your professionalism and hard hard work. Thanks again.
